TRUCK.

.Application filed May 22, 1924.v Serial No. 715,239.

To all calzoni 'it may conce "n:

it linovn that l, .flvoi'rN J. FLOYD, a citizen of the United States ofAmerica, and a resident of lrlalden, in the county of Middlesex andCommonwealth of Massachusetts, have invented certain new and usefulImprovements in Trucks, of which the following is a specification.

This invention relates to a truchand more particularly to a truckadapted for use in the printing trade wherein type forms of considerablesize and weight are frequently moved from place to place, whichoperation has heretofore required the services of two worlunen and acrude truck or conveyance.

in object of the invention isv to provide a. truck of this class thatmay be loaded and unloaded hy one workman in a rapid and energy savingmanner and with safety to the type forms being handled.

il further object of the invention is to so construct a truck of thisclass that it may be made to function asa stationary table or platformwhile receiving or delivering a type forni, and which may be rapidlymade to function as a rolling conveyance when required.

it still further object of the invention is to so construct and arrangethe form receiving platform that it may be rapidly adjusted touccomn'iodate it to the height of a form receiving or delivery pointsuch as a maire-up stone, and which may be swul'ig into an approximatelyvertical' position for the reception or delivery of type forms from ortolloor racks such as are commonly used in printing establishments.

rinother object of the invention to so arrange the forni receivingplatform that the major portion of the weight of the type forni mountedthereon is borne by the'truck frame during the transporting operation,or when the said plata-form is in an approximately vertical position.

lt also an object of the invention to so construct and arrange a truckof this class that a forni placed thereon may be locked thereto and theweight thereof positioned to the best advantage for the transportingoperation.

'lo theattainnient of the above objects the invention consists incertain novel features of construction and arrangement of parts hichwill hereadily understood by reference to the description of thedrawings and to the claims hereinafter given.

Forthe purpose of illustrating4 the invention, one preferred formthereof isy illustrated in the drawings, this form having been found togive satisfactory and reliable results, although it is to be understoodthat the various instrumentalities of which the invention consists canbe variouslyarranged and organized, and that the invention is notlimited to the precise arrangements and organizations of theinstruinentalities herein shown and described, except as required by thescope of the appended claims.

Figure 6 is Figure 2.

Figure' 7 is Figure 2.

Figure 8 is a detail of a. locking means to be described` Like4characters represent like parts throughout the several figures of thedrmvings.

Referring to the drawings:

The drawings hereuiith represent the invention as applied to a 'truckparticularly intended for use in a printing establisha section on theline 6-6 a section onthe line 7-" ment wherein type forms are requiredto' be moved from one place to another, hut it will be understood thatchanges might he made therein to lit it for other uses without departingfrom the spirit and scope of the invention.

The truck frame lO having two sets of wheels 1l and l2 is also providedwithframe elevating levers 13 and 14 under the control of a hand leverl5, said lever being adapted to at all times elevate the Itrucksulliciently to remove the said wheels from contact with ra'rENT tid thelicor, and when the said levers are locked by the latch 16 with thewheels in the said position, the truck becomes substantially immovable,particularly against accidental movement when loading or unloading. I

lhe trame 1() has uprights 17 andlS which have bearings 19 at the topsthereo't `for trunnions 2O ot a table carrying frame 21 to which ispivotally mounted the table 22 by means ol.t links 23.

The trunnions 2() are in vreality extensions et a crank shaft 2li whichcarries the links 25 pivotally connected to the table 22, and the link2T pivoted to a block 28 which in turn is swiveled to the short link 2Opivoted to the short arm of the bell crank lever Si).

The bell crank 3() is pivoted to the traine 21 at 3l and has a lever 32pivoted at 323 adapted to coact therewith to lock it in a givenposition.

The table 22 and the 'trame 2l each have hooks let and respectively toreceive a 'torni F, while the table also has other hooks 3G adapted toslide on rods 3T and to be secured to said rods by set screws 3S, andwhen not in use these hooks BG will be swung downwardly out or the wayof an oncoming or oli' going type vtorni or chase as shown by full linesl igure 1.

Fast to the trame 2l. a ratchet segment which is normally engaged by apawl 40 pivotally attached under spring centrol with the upright 17.

fr segmental shoe `tl adapted to at times cause the pawl a() to bedisengaged from the ratchet 39, is pivoted at 42 to the frame 21 and hasa stud t3 extending therefrom and entering an inclined slot la ot' ahead a5 tast on the rod 46 which is slidingly mounted on the trame 21and under the control ot a spring 417, and has a knob 4S adapted to behand pressed when it is desired to disengage the said pawl L5t() tromthe ratchet 35).

To retain the table and its Carrier Yframe 21 in the position shown inFigure 4, a' pawl is suitably pivoted to the upright 18 and .adapted toautomatically engage a pin on the frame 21., and may be releasedtheretrom by foot pressure when it is desired to swing the table and itscarrier into the position shown in Figure 1 ot the drawings.

To support the carrier and table as seen in l `igures 1 and 2 legs 50and 51 are provided, and comprising brackets 52 and each ot which ispivoted to an inclined stud 5st, and adjust-able extensions The legs aretubes closed at the lower ends and 'tast with the brackets 52 and 53 andwhich have slidably mounted therein the tubular extension rods betweenthe upper ends ot which and the lower ends ot kthe legs 50 areinterposed the springs 5G which tend to force the said extensionsupwardly but may be restrained trom so doing by the set screws When thelegs 50 and l are out of operation as seen in Figures and 5 they areheld :trom swinging outwardly by means et the latch 5S pivoted to thebracket which automatically engages the pin 59 when the legs arepositioned as seen in the said ligures.

The studs 54 are oppositely inclined as seen in Figure 5 so that whenthe legs 50 and 5l are swung from the positions shown in Figures 1 and 2to those ot' Figures it and 5, the said legs will be automaticallyraised from floor contact in order that the truck may be rolled.

Then the said legs are swung outwardly the incline of the studs is suchthat the said. legs will meet the floor during some part ot' theirmovement so that iirm and equal support will be atl'orded the 4trame 21and table 22 even though the lloor upon which the truck rests may beuneven.

To operate the truck, let it be supposed that a form has been placed onit and moved to its destination, as itor instance a .tloor rack, whereinthe iorms are placed on edge in the several con'ipartments.

Having arrived with the rack with the truck in the condition shown inFigures 4 and 5 of the drawings, the latch 1G will be tripped to permitthe hand lever 15 to be swung to the right to cause the elevating leverslet to engage the lioor and raise the truck until the weels 11 and 12are free from door contact whereby the truck becomes substantiallyimmovable.

The set screws 3S will now be released and the hooks or dogs 36 will bedisengaged trom the form F which is now ready to be slid oitl the truckinto its place in the rack.

It however it is desired to deliver the torm to a makeup stone, or to apress where` it is to be placed face up, the truck will be elevated bythe hand lever 15 as before explained, the latch 58 will be tripped andthe legs 50 and 51 swung outwardly till they meet the iloor.

The latch Lt9 will now be tripped to rclease the trame 21 which may beswi'ing on its trunnions 2O till the bearing wings GO meet the extensionrods 55, which it will be supposed had been previously adjusted toapproximately the height required, but may be further adjusted itnecessary and secured in such position by the set screws 57.

It at this time the frame 21 and table are approximately level and thetable 22 at approximately the right height, no further adjustmentthereof will be necessary, in which case the dogs will be released asbetere fil and the :torni slid oil on to the inake-upstonc or prese as;the case may be.

(ln the other hand if the table 22 is not level but at this time assumesthe posit' n shown in Figure T, and it ie necessary to make it assumethe position o'-ligure 67 the lever 3d will be forced outwardly,ca'ueing;v the links 2S) and 279 through the block 2li, io rock theshait )A and gi ve longitudinal movement to the table 22 through thelinke 23 which will swing` on their pivots 23X until the end of thetable (i5 meets the end strut 2l of the trame 2l.

rlhie last movement is .suflicient to therea ter permit a pivotalmovement ot the table about the pivots G6, as at that time the table end67 is removed 'trom under the hooks 35 and further rocking ot the shai't2l will cause the said. table 22110 swing on the pivotel (SG into theposition shown in Figure (l, at which time the locking rod 32 may bemade to engage one ot the notches (SS ot the lever 30 to thereby lock itin position against lowerim;- movement oi the table.

'lo prevent the table Q2 'trom being swfung; on thc pivots (5G bci'orethe cud (35 meetsl the strut 2lX ot the iiran'ie 2l, am to lock the said.i able against longitudinal movement` while in the position of lligure(i, the tollowing means is employed.

llast to the table is a hook like bunter T0 adapted to at times engagethe under side or edge oi" a lug Tl when the table and Atraine 2l are inthe positions .shown in Fig? urcs l and T thus holding' them toeetherand preventing swinging' movement o' the table until the longitudinalmovement has been accomplished, at which time the bunter is ireed 'fromthe under side ot the lug and the table may then be swung.

After the table has been swun` the said bunter will abut the side edgeolf the lug and thereby prevent retrograde longitudinal movement oi thesaid table until such time as it has lirst been lowered so that the saidbunter is free ot the side edge and ready lo engage the lower edge whichis plainly illustrated in ligures T and S ol" the drawings.

To restore the truck to the position ol' Figure el from that oit Figurel, the locking` rod will be released from its notch in the lever 30, andsaid lever will be 'forced in- 'ardly, causinggl the link 27 to rock theshalt 2l and swing` the table on its pivots GG until it finds its properresting?)` place and with the bunter 'TO free from the side edge oi theliu;v 7l and ready to engage the under edge thereoli. v

Further movement of the lever 30 at this time will cause the links 223to Swing on their pivots and give a longitudinal movement to the tableQ2, which movement will bring an edge ot the chase, it on the table,under the hooks 35, and engagement ot the bunter and under edge et thelug will take place and prevent accidental swinging ot `the table untilthe proper time. i

The knob 48 will now be pressed. which will cause the cam slot to deprithe piu 443 and swing the Shoe il on its pivot 4i?, which action forcesthe pawl 40 out of engagement with the ratchet BQby reaaonof the shoe-ll striking` the pin 1i-0K oi' the pawl h).

rlhe frame and table may now be swung into the position Shown in FigureLl at which time the latch 4-9 will automatically engage its pin andlock the ,traine in that po sition.

The bracket 52 will now be swung toward the truck, and next the bracket553, until. the pin 5l) is engaged by the latch fl or mue locking` bothbrackete in the positions shown in Figure 5 oi the drawings.

It at this time it is desired to roll the truck about the door, the handlever l5 will be moved from position shown in Figure E2 to that shown inFigure 5, artter Vtiret having;l tri pped the pawl lo, whereby theelevating levers will now resume the positions shown in Figure 5 withthe wlieele 1l andy l2 in contact with the tloor.

The lever lli is so arranged that the brackets 52 and 53 cannot swim;-outwardly until the said lever has been moved to raifse the truck,thereby providinga safety lock 'tor the brackets and compelling thcoperator to first stop the truck and elevate it before swinging thetableto receive or discharge .a torni.
